HATCHED AREAS MUST BE COVERED WITH
NON-COMBUSTIBLE MATERIALS ONLY.
FINISHING MATERIALS INSTALLATION
All finishing materials that surround this fireplace’s arch profile must extend out from the face surface of this fireplace 1
inch minimum for most decorative Fronts to fit properly. A maximum finishing material thickness of 2.5” is allowed.
FINISHING GUIDES
This appliance arrives with the inner finishing
guides factory installed. When installing a Grace
Front, Willowbrook Front or Bentley Doors on
the fireplace there are two options for finishing
the fireplace depending on the finishing material
and desired look. The fireplace can be finished
to the inner guides that come on the fireplace or
the guides that come with the front kits can be
installed on the fireplace and used as outer fin-
ishing guides. For more information reference
the instructions that come with the front kits. If
the finishing material is greater than 2.5” thick
the guides that come with the fronts must be
used.
Tiles and Faux Rock
If installing Tiles or Faux Rock, first install a ½” thick (minimum) (Backer board) over the face of the fireplace and framing
members. Follow by applying Thin Set mortar (no polymer additives) using ¼” square notched trowel on the cement board
surface. Finally, install tile to reach a finish material depth of 1 inch.
Marble and Granite Slabs
If installing Marble or Granite slabs as fascia materials, specify that the inner edges that will be adjacent to the Glass Door
are polished. Rough Framing should be created at 14-1/8” depth with the front surface of this fireplace protruding out ½”
from the framing surface. Install 1/2'” thick drywall on framing members so that its outer surface is flush with the front face
of this fireplace. Attach Marble or Granite slabs to face of unit and to drywall surface using adhesive that does not off gas
when hot. Mendota recommends using High Temperature RTV Silicone 1/8” round beads in serpentine lines over the
metal face of the unit to adhere the marble or Granite slabs. Never use large pools of RTV silicone. Only 1/8” round beads
in spline shapes are permitted. Allow at least 24 hours or longer per manufacturer’s recommendations for the RTV Sili-
cone to cure before operating this appliance. Failure to allow adequate cure time can result in the RTV silicone oozing out
of joints or the RTV can off-gas pungent odors.
In the area defined as “NONCOMBUSTIBLE ZONE” [FIGURE 7], only NONCOMBUSTIBLE MATERIALS ARE
ALLOWED. Mendota Recommends the use of an R1.0 or higher rated Backer ½” board as base material in the non-
combustible zones. DO NOT use Durock or Wonderboard. These materials breakdown when heat is applied and are not
recommended.
When this fireplace is installed in a framed cavity that is 14-5/8” deep, the facing material finishing guide will protrude out
into the room 1 inch. Build finishing materials to 1 inch thickness and use the built-in guides for edge alignment of fascia
material. Consult section “FRAMING DEPTH and FINISHING
GUIDES”.
WARNING
: The cross hatched areas labeled as
“NONCOMBUSTIBLE ZONE” must be covered with noncom-
bustible finishing materials that is 1-inch thick, minimum. DO
NOT ALLOW COMBUSTIBLE FACING MATERIALS TO
ENCROACH IN THIS AREA!
